AUTOMATIC SIGHT-FEED` LUBRICATOR.

SPECIFICATION forming part of Letters Patent No:V 508,566, dated November 14, `18593.

bricators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skllled 1n the art to which it appertains to makeand use the same, reference being had to Y the accompanying drawing, and to letters of reference marked thereon, which form a part of this specification. Y

This invention relates to certain improvements in what are commonly called automatic sight-feed lubricators, for 'feeding oil automatically to water heaters, boilers and the like.

The objects of the invention are to cause the feed pump to serve in regulating the feeding of the oil and to secure a regular and effective supply, to increase the size of the oil drops supplying thelubricant, to simplify the construction and reduce the cost ot' manufacture, and to secure other advantages and results some 'of which will be referred to in connection with the description of theworkin g parts,

The accompanying drawing illustrates, in central vertical section, the novel features of construction in my invention', the one figure being deemed sufficient to fully exhibit thev improvements.

In sald drawing, a indicates a vessel containing, or adapted to contain, a body of oil and water, the oil, a', being lighter than-the water, a2, ioatin'g on the latter as indicated.

At the upper and lower ends of the said ves-l sel, openings are provided, the purposes of which will be duly explained. At the opening, a3, is arranged and secured an iniiow pipe or duct, h, which extends upwardly, as at h', from the vessel and is bent or turned horizontally, as at b2, and the horizontal portion, b2, being provided with threaded protuberances b3, b4, which are centrally open to provide a passage for fluid.

By means of the horizontal portion, b2, and the continuation or extension, h6, of the same,

I am enabled to enter the mainfeed waterv pipe at its side and `thus sediment in said feed water pipe is prevented from working into the Sight tube and `obstructing the flow there- ApplicationiiledMay 18,1893. Seria'lNo.4' 74,654- ((No model.) i

through, the said feed water pipe being larger in diameter than said pipe, b2, and the bottom of the bore therein being below the bottom of said pipe b2 as will be understood. Again by means of the turn in the pipe, b, and the entrance of the horizontal parts being aty the side of the feed water pipe as described, the sight-glass is brought to a higher elevation where it may be more conveniently inspected.

At the side of the opening, d3, tle distance therefrom, is another opening, a4, which lies vertically in line with the openings, in the horizontal portion, b2.y At said opening, a4, is formed a conical projection, a5, and, around it, a threaded nipple, a6, an annular recess being formedV between yto receive the end of the sight glass or transparent tube, c. Said transparent tube extends upward from the annular recess into the opening in the protuberance, b4, and the joints around the same arevrnade impervious to water by suitable packing employed in connection with the glands or followers d, e, or otherwise. The conical projectioninwhich the opening or passage, agis4 formed extends upward a distance into said tube and is provided with a pin or rod,f, which is smaller in diameter than said passage or that the latter is given and 3.1mm-

an annular form as will be understood. Said pin or rod terminates at or just short of the extremity of the conical projection and thus lthe globule of oil collecting at the end of the conical projection holds to said projection until it has gained considerable size, when it severs its connection from the said projection because of the smaller specific gravity of the oil and rises through the water, lying insaid tube, c,-to the horizontal tube portion, b2, where it .is fed in small quantities, but regularly, into the boiler or heater automatically. By means .of the pin, rod or wire, f, a broad extremity of the projectioma, and a broad supply opening, a4, but Vthe area of said opening is reduced so that the oil is fed but slowly. v

The flow through the annular opening, a4, may be regulated by means of a connecting rod, f', having at its connection with theV pin orQrod, f, a, conical shoulder, f2, which, may engage a correspondingly conical seat, f3, to close the passage or opening a4. The rods f and f may be of one integral piece.- The IOS ` the feed water pipe.

the ller plug as.

pump, I prefer to-employ,in connection withthe horizontal pipe portion, b2, and in line with the transparent tube, c, an air chamber, b5, which when in normal 'operation is partly lled with air at the top and with oil at theV bottom, the mouth of the chamber lying downward and in line with the projection a5, so that the oil rises into the said mouth .directly. to one side or the other of said line.l

In operating the device thus described, the parts being constructed and assembled in the manner stated, and the horizontal portion, b2, being secured to the feed water pipe of the boiler or heater by means of the pipe section, b, of the feed water pipe I first close communication with the vessel, a, through the pipe, h6, by means of a suitable valve, and close the regulating valve by turning the screw, f4, so that tiuid cannot pass through the opening, a4. I then open a drain cock, a7, and allow any water that may be in the vessel, d, to be discharged therefrom, the said vessel being vented, to allow such discharge, by removing After the water has run out and the cock, a7, closed, the valveff", and the valve or cock of the pipe, be, (not shown) opened, the further action of the device is automatic in regularly feeding the oil to the boiler. As the oil rises through the projection a5 and the water in pipe, c, it enters the chamber b5 aud gradually takes the place of the water that previouslyentered from The AHuid pressure on the air in said chamber compresses the said air and thelatter serves as an elastic cushion which relieves other parts which would otherwise work irregularly and without the cer-L tainty which would enable vthe engineer to know when to replenish the vessel. When water already under high pressure is used and a pump for feeding the boiler is dispensed With, I may dispense with the air chamber.

After the filling of the lowerpart of the chamber, b5, with oil, the subsequently supplied oil is fed outward through the pipe b2, b, the water from the supply pipe iiowing inward to take its place and, being heavier than the oil, the water iiows downward through an interior extension, g, of the pipe, b, raising the oil so that it will flow upward through the opening, a4, regularly but slowly.

It may however be disposed a little tremity ofthe projection, a5, the oil meets with cates the same, so as-to prevent foaming and to siecureother well known advantages connected with the use of kerosene or other light mineral oils. The aiiiuity of the oil for the metal of the horizontal pipe, b2, helps iu securing a free flow over the-water and against thecurrentof said waterin said pipe. When the pump and air chamber are used, the 'action of the pump on the compressed but elastic air, through the fluids lying in the pipe b2, b, and air chamber, produces a pumping action 'onrtheoil so that `the latter lying in the horizontal pipe is helped in its outiiow.
